This is a minor change that avoids a cluster-wide query for active listeners. The old code called `rabbit_networking:active_listeners/0` and then filtered the results by ones available on the local node. This caused an RPC and concatenation of all other cluster members' listeners and then in the next line filtered down to local nodes. Equivalently we can use `rabbit_networking:node_listeners(node())` which dumps a local ETS table. This is not a very impactful change but it's nice to keep the latency of the health-check handlers low and reduce some unnecessary cluster noise.
This updates the health check for protocol listeners to accept a set of protocols, comma-separated. The check only returns 200 OK when all requested protocols have active listeners.

@the-mikedavis thank you, I'm on it. FYI, the HTTP API reference was moved to the website. It's fine to update the bits in this repo, of course, but the plan is to eventually only have a website link. |

Ah I see that in the website repo now. I'll add the updates for this and #13872 (and the future health-check PRs) in some PRs to the website repo too 👍 |

This PR also adds a commit which changes the helper used to look for active listeners from
rabbit_networking:active_listeners/0torabbit_networking:node_listeners(node())- this eliminates some unnecessary RPC calls. It's unrelated to the feature part of this change.
